Description

DESCRIPTION

Interference coordination method and apparatus, base station and user equipment

technical field

The present disclosure relates to the field of communication technology and, in particular, to a method and apparatus for coordinating interference, a base station, user equipment, and a computer-readable storage medium.

Background

With the rapid development of wireless communication technology, a 5th generation (5G) mobile communication technology has emerged. In the initial phase of 5G design, a non-autonomous device (NSA) is used for network deployment. That is, long-term evolution (LTE) is used as the main coverage, new radio (NR) is used as a powerful complement for data transmission services, to form an interconnection design of LTE-N ^r . In this way, it can not only take full advantage of the existing network coverage of LTE, but also gradually switch to 5G NR, so that the network transition is smoother and more stable.

Currently, popular network frequencies for NR are 3.4GHz - 4.2GHz, 4.99GHz, 24GHz and so on. Among them, 3.4 GHz in the low frequency band particularly receives more attention, and many operators preferably deploy 5G NR with a frequency of 3.4 GHz - 3.6 GHz.

However, LTE has a large number of devices operating in the frequency range of 1.7 GHz -1.8 GHz, such as the usual frequency division double (FDD) band 3 and so on.

The user equipment (UE) can work in an LTE frequency band and a NR frequency band at the same time and can also work in two frequency bands for NR. When interconnection occurs in two frequency bands, there may be mutual interference problems between uplink and downlink transmissions in the two frequency bands. At present, the problem of mutual interference is solved by avoiding simultaneity of the two frequency bands, that is, either by activating one frequency band or by activating another frequency band. However, this method requires frequently activating different frequency bands, which wastes UE resources and affects the user experience. For example, methods and apparatus for mitigating device interference are described in US Patent Application Publication No. US2012/0207040A1. The methods may include a device interference event (eg, a jamming situation) and event processing may depend on the priority of the technologies. A handover to another frequency or radio access technology (RAT) may occur if a coexisting technology can be activated. The network can tell the device a list of frequencies or RATs that it can be allowed to measure and handoff. A network can provide a scaling value that the device can use to speed up reaction to interference. The device may apply a scaling factor to an "out of sync" counter and/or to the radio link failure (RLF) timer used for the RLF procedure. The device can apply different scaling factors for measurements and time to trigger events. The device can trigger a report to the network asking for slots for an alternate RAT.

Detailed description of the examples

Examples will be described in detail herein, with illustrations thereof depicted in the drawings. Where the following descriptions involve the drawings, like numbers in different drawings refer to the same or similar elements unless otherwise indicated. The examples described in the following examples do not represent all examples consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of this disclosure as detailed in the appended claims.

Fig. 1 is a flowchart illustrating an interference coordination method according to an example of the present application. This example is described from a base station side. As shown in Fig. 1, the interference coordination method includes steps S101-S102.

In step S101, it is determined whether there is interference in the device between uplink and downlink transmissions by the UE in two frequency bands.

In this example, the base station can determine whether there is in-device interference between uplink and downlink transmissions by the UE in the two frequency bands based on information about the UE accessing a network in the that interference in the device may include harmonic interference and intermodulation interference.

When integer multiples of one frequency band overlap at least partially with another frequency band, harmonic interference can occur between uplink and downlink transmissions in these two frequency bands.

Intermodulation interference (IM interference) refers to the fact that when two or more interfering signals are added to a receiver at the same time, due to a non-linear effect, the frequencies of the resulting components formed by the interfering signals are sometimes the same. or close to a frequency of a desired signal, and thus the resulting components pass directly through the receiver and cause interference.

In step S102, if there is interference in the device between the uplink and downlink transmissions, downlink in the two frequency bands by the UE, configuration information is sent to the UE, in which the configuration information is used to indicate to the UE, in a time interval during which the base station sends control data of a downlink transmission in one of the two frequency bands, that stops an uplink transmission in at least one of the two frequency bands or performs power reduction for the uplink transmission in the at least one of the two frequency bands.

In this example, if the base station determines that device interference, such as harmonic interference or intermodulation interference, exists between the uplink and downlink transmissions by the UE in the two frequency bands, the base station The base station may send configuration information to the UE, and the UE may stop an uplink transmission in at least one of the two frequency bands in a time interval during which the base station sends control data of a downlink transmission. in one of the two frequency bands according to the configuration information, thereby avoiding interference for a control channel in the device. And the UE may also perform power reduction for an uplink transmission in at least one of the two frequency bands in a time slot during which the base station sends the downlink transmission control data in one of the two frequency bands. the two frequency bands according to the setting information, thereby achieving a goal of reducing interference for the control channel in the device.

In the example, when it is determined that the interference exists in the device between the uplink and downlink transmissions in two frequency bands by the UE, the configuration information is sent to the UE, so that the UE can stop the transmission. uplink transmission in at least one of the two frequency bands or perform power reduction for the uplink transmission in the at least one of the two frequency bands in a time interval during which the base station sends data downlink transmission control in one of the two frequency bands, thereby achieving the goal of reducing interference for the control channel in the device.

Fig. 2A is a flowchart illustrating another interference coordination method according to an example of the present application. This example is described from a base station side. As shown in Fig. 2A, the interference coordination method includes steps S201-S203.

In step S201, it is determined whether there is harmonic interference or intermodulation interference between uplink and downlink transmissions in two frequency bands by the UE. If the harmonic interference is determined to exist between an uplink transmission in a first frequency band and a downlink transmission in a second frequency band by the UE, step S202 is performed, and if the interference is determined to exist intermodulation between uplink transmission in both a first frequency band and a second frequency band and a downlink transmission in the first frequency band by the UE, step S203 is performed.

In this example, the base station can determine whether there is harmonic interference or intermodulation interference between the uplink transmission and downlink transmission, by the UE, in the two frequency bands based on information about the accessing UE. to network. In order to improve the decision accuracy, it is also possible to firstly receive interference tolerance capability information notified by the UE, and then determine whether there is harmonic interference or intermodulation interference between the uplink transmission and downlink transmission, by the UE, in the two frequency bands according to the interference tolerance capability information and the information of the UE accessing the network.

The first frequency band may belong to a frequency band for LTE and the second frequency band may belong to a frequency band for NR. Alternatively, the first frequency band and the second frequency band may also belong to two frequency bands for NR respectively.

Assuming that the first frequency band is an LTE frequency band and the second frequency band is an NR frequency band, as shown in Figure 2B, uplink (UL) transmission harmonic waves 21 in the LTE frequency band may cause interference with downlink (DL) 22 transmission in the NR frequency band for the UE. As shown in Figure 2C, intermodulation components formed by the uplink transmission 24 in the LTE frequency band and the uplink transmission 25 in the NR frequency band can cause interference with the downlink transmission. 26 in the LTE frequency band for the UE.

In step S202, a first time slot for sending downlink transmission control data in the second frequency band is determined, and first configuration information is sent to the UE, in which the first configuration information is used. to instruct the UE to stop the uplink transmission in the first frequency band in the first time slot or to send the uplink transmission in the first frequency band at a reduced transmit power in the first time slot weather.

The control data may include control signaling and a reference signal, or may include only control signaling. Control signaling may include, but is not limited to, a physical downlink control channel (PDCCH). The first configuration information may be carried in broadcast signaling, upper layer signaling, or physical layer control signaling, sent by the base station.

In this example, after the base station determines that harmonic interference exists between the uplink transmission in the first frequency band and the downlink transmission in the second frequency band by the UE, the base station can determine a first time interval during which downlink transmission control data has to be sent in the second frequency band, and send first configuration information to the UE, so that the UE can stop the uplink transmission in the second frequency band. first frequency band or sending the uplink transmission in the first frequency band at a reduced transmission power in the first time slot.

Taking Figure 2B as an example for description, after the base station determines that the harmonic interference exists between the uplink transmission in the LTE frequency band and the downlink transmission in the NR frequency band by the UE, the base station may determine a first time slot for sending downlink transmission control data in the NR frequency band, and send first configuration information to the UE. After receiving the first configuration information, the UE may stop uplink transmission in the LTE frequency band at the first time slot according to the first configuration information, to avoid harmonic interference. After receiving the first configuration information, the UE may also send the uplink transmission in the LTE frequency band at a reduced transmission power according to the configuration information, to reduce harmonic interference.

Furthermore, when the control data only includes control signaling, the first configuration information may include a first interference coordination policy, and the first interference coordination policy may include: that the UE delay sending the transmission of uplink in the first frequency band for the duration of the first time slot, or a first set power value at which the transmit power is to be reduced. In this way, after receiving the first configuration information, according to the first interference coordination policy, the UE can delay sending the uplink transmission in the first frequency band at least for the duration of the first time slot, or sending the uplink transmission in the first frequency band at a transmission power reduced by the first set power value. Delaying sending the uplink transmission in the first frequency band at least for the duration of the first time slot is a case of stopping the uplink transmission in the first frequency band in the first time slot.

In step S203, a second time slot for sending downlink transmission control data in the first frequency band is determined, second configuration information and third configuration information are sent to the UE. The second configuration information is used to tell the UE to stop the uplink transmission in the first frequency band in the second time slot or to send the uplink transmission in the first frequency band at a transmission power reduced by the second time interval. The third configuration information is used to tell the UE to stop the uplink transmission in the second frequency band in the second time slot or to send the uplink transmission in the second frequency band at a transmission power reduced by the second time interval.

The second configuration information may be carried in broadcast signaling, upper layer signaling, or physical layer control signaling, sent by the base station, and the third configuration information may also be carried in broadcast signaling, upper layer signaling. or the physical layer control signaling sent by the base station.

In this example, after the base station determines that intermodulation interference exists between the uplink transmission in both the first and second frequency bands and the downlink transmission in the first frequency band by the UE, the base station may determine a second time slot for sending the downlink transmission control data in the first frequency band, and send the second configuration information and the third configuration information to the UE. Thus, in the second time slot, the UE may stop the uplink transmission in the first frequency band or send the uplink transmission in the first frequency band at a reduced transmission power, and in the second time slot of time, the UE may stop the uplink transmission in the second frequency band or send the uplink transmission in the second frequency band at a reduced transmission power, thereby reducing intermodulation interference.

Taking Fig. 2C as an example for description, after the base station determines that the intermodulation interference exists between the uplink transmission in both the LTE frequency band and the NR frequency band and the uplink transmission downlink transmission in the LTE frequency band by the UE, the base station may determine a second time interval during which the downlink transmission control data in the LTE frequency band is sent, and send second transmission information. configuration and third configuration information to the UE. After receiving the second configuration information and the third configuration information, the UE may stop the uplink transmission in both the first frequency band and the second frequency band at the second time slot according to the second configuration information and the third configuration information, to avoid intermodulation interference. After receiving the second configuration information and the third configuration information, the UE may also send the uplink transmission in both the first frequency band and the second frequency band in the second time slot at a reduced transmit power according to the second configuration information and the third configuration information, to reduce intermodulation interference.

Furthermore, when the control data only includes control signaling, each of the second configuration information and the third configuration information may include a second interference coordination policy, and the second interference coordination policy may include: that the UE delay sending the uplink transmission in both the first frequency band and the second frequency band for the duration of the second time slot, or a second set power value at which the power of the transmission has to be reduced transmission. In this way, according to the received second interference coordination policy, the UE can delay sending the uplink transmission in both the first frequency band and the second frequency band for at least the duration of the second time slot , or sending the uplink transmission in both the first frequency band and the second frequency band at a transmission power reduced by the set second power value. Delaying sending the uplink transmission in both the first frequency band and the second frequency band for at least the duration of the second time slot is a case of stopping the uplink transmissions in the first frequency band and in the second frequency band in the second time slot.

In the example, after determining that the harmonic interference exists between the uplink transmission in the first frequency band and the downlink transmission in the second frequency band by the UE, the first time slot for sending the downlink transmission control data in the second frequency band, and the first configuration information is sent to the UE, so that the UE can stop the uplink transmission in the first frequency band in the first interval of time or send the uplink transmission in the first frequency band at a reduced transmission power in the first time slot, thereby achieving the goal of reducing harmonic interference. Further, after determining that the intermodulation interference exists between the uplink transmission in both the first frequency band and the second frequency band and the downlink transmission in the first frequency band by the UE, the second time slot for sending the downlink transmission control data in the first frequency band, and the second configuration information and the third configuration information are sent to the UE, so that the UE can stop transmitting uplink in both the first frequency band and the second frequency band in the second time slot according to the second configuration information and the third configuration information, or send the uplink transmission in both the first frequency band and in the second frequency band at reduced transmit power in the second time slot or, thereby achieving the goal of reducing intermodulation interference.

Fig. 3 is a flowchart illustrating yet another interference coordination method according to an example of the present application. This example is described from a UE side. As shown in Fig. 3, the interference coordination method includes steps S301-S302.

In step S301, configuration information is received, which is sent by a base station after determining that there is interference in the device between uplink and downlink transmissions by the UE in two frequency bands.

In this example, the base station may send the configuration information to the UE after determining that interference exists in the device between the uplink and downlink transmissions in the two frequency bands by the UE. Device interference can include harmonic interference and intermodulation interference.

Optionally, in order to improve the interference determination accuracy for the base station, the UE may also notify interference tolerance capability information thereof to the base station, so that the base station can determine whether the interference exists. harmonic or intermodulation interference between the uplink and downlink transmissions in the two bands of frequency by the UE based on interference tolerance capability information and information about the UE accessing a network.

In step S302, according to the configuration information, at a time interval during which the base station sends downlink transmission control data in one of the two frequency bands, the uplink transmission in at least one of the two frequency bands, or power reduction is performed for the uplink transmission in the at least one of the two frequency bands.

According to the configuration information, the UE may stop the uplink transmission in at least one of the two frequency bands or perform power reduction for the uplink transmission in the at least one of the two frequency bands in a slot. of time during which the base station sends downlink transmission control data in one of two frequency bands, thereby achieving a goal of reducing interference for a control channel in the device.

In the example, after receiving the configuration information, according to the configuration information, in a time slot during which the base station sends the downlink transmission control data in one of the two frequency bands, the UE can stop the uplink transmission in at least one of the two frequency bands or perform power reduction for the uplink transmission in the at least one of the two frequency bands, thereby achieving the goal of reducing interference for the control channel on the device.

Fig. 4A is a flowchart illustrating yet another interference coordination method according to an example of the present application. This example is described from a UE side. As shown in Fig. 4A, the interference coordination method includes steps S401-S402.

In step S401, first configuration information is received, which is sent by the base station after determining that harmonic interference exists between the uplink transmission in a first frequency band and the downlink transmission in a second frequency band by the UE and determining a first time slot during which downlink transmission control data has to be sent in the second frequency band.

The first frequency band may belong to a frequency band for LTE, and the second frequency band may belong to a frequency band for NR. Alternatively, the first frequency band and the second frequency band may also belong to two frequency bands for NR respectively.

The control data may include control signaling and a reference signal, or may include only control signaling. Control signaling may include, but is not limited to, a PDCCH. The first configuration information may be carried in broadcast signaling, upper layer signaling, or physical layer control signaling, sent by the base station.

In this example, after the base station determines that harmonic interference exists between the uplink transmission in the first frequency band and the downlink transmission in the second frequency band by the UE, the base station can determine a first time interval during which downlink transmission control data has to be sent in the second frequency band, and send first configuration information to the UE.

In step S402, according to the first configuration information, the uplink transmission in the first frequency band is stopped at the first time slot or the uplink transmission in the first frequency band is sent at a transmission power reduced in the first time interval.

After receiving the first configuration information, the UE may stop the uplink transmission in the first frequency band in the first time slot, or send the uplink transmission in the first frequency band at the transmission power reduced by the first time interval.

For example, as shown in Fig. 4B, there is harmonic interference between an uplink transmission in frequency band F1 and a downlink transmission in frequency band F2 by the UE. The downlink transmission control data in the F2 frequency band includes a PDCCH 41 and a reference signal 42. To avoid harmonic interference, the UE may stop the uplink transmission in the F1 frequency band at a certain time. first time slot 43. To reduce harmonic interference, the UE may send the uplink transmission in frequency band F1 at a reduced transmission power in the first time slot 43.

Furthermore, when the control data only includes control signaling, the first configuration information may include a first interference coordination policy, and the first interference coordination policy may include: that the UE delay sending the transmission of uplink in the first frequency band for the duration of the first time slot, or a first set power value at which the transmission power is to be reduced. In this way, after receiving the first configuration information, according to the first interference coordination policy, the UE can delay sending the uplink transmission in the first frequency band at least for the duration of the first time slot, or sending the uplink transmission in the first frequency band at a transmission power reduced by the first set power value. Delaying sending the uplink transmission in the first frequency band at least for the duration of the first time slot is a case of stopping the uplink transmission in the first frequency band in the first time slot.

For example, as shown in Fig. 4C and Fig. 4D, harmonic interference exists between an uplink transmission in frequency band F1 and a downlink transmission in frequency band F2 by the UE. The downlink transmission control data in the frequency band F2 includes a PDCCH 44. In order to avoid harmonic interference, as shown in Fig. 4C, the UE may delay sending the downlink transmission. uplink in the F1 frequency band for the duration of the first time slot 45. As shown in Fig. 4D , in order to reduce harmonic interference, the UE may send the uplink transmission in the F1 frequency band at a reduced transmission power in the first time slot 45.

In the example, after receiving the first configuration information sent by the base station, according to the first configuration information, the uplink transmission in the first frequency band may stop at the first time slot or the uplink transmission at the first frequency band is sent at a reduced transmission power in the first time slot, thereby achieving a goal of reducing harmonic interference.

Fig. 4E is a flowchart illustrating yet another interference coordination method according to an example of the present application. This example is described from a UE side. As shown in Fig. 4E, the interference coordination method includes steps S403-S404.

In step S403, second configuration information and third configuration information are received, which are sent by the base station after determining that intermodulation interference exists between the uplink transmission in both a first frequency band and a second frequency band. downlink transmission in the first frequency band by the UE and determining a second time interval during which the control data of the downlink transmission in the first frequency band has to be sent.

The second configuration information may be carried in broadcast signaling, higher layer signaling, or physical layer control signaling sent by the base station, and the third configuration information may also be carried in broadcast signaling, upper layer signaling, or the physical layer control signaling sent by the base station.

In this example, after the base station determines that intermodulation interference exists between the uplink transmission in both the first and second frequency bands and the downlink transmission in the first frequency band by the UE, the base station may determine a second time slot for sending the downlink transmission control data in the first frequency band, and send the second configuration information and the third configuration information to the UE.

In step S404, according to the second configuration information and the third configuration information, the uplink transmissions in the first frequency band and the second frequency band are stopped or the uplink transmissions in the first frequency band are sent. frequency and in the second frequency band at a reduced transmit power in the second time slot.

After receiving the second configuration information and the third configuration information, the UE may stop the uplink transmission in both the first frequency band and the second frequency band in the second time slot or send the uplink transmissions in both the first frequency band and the second frequency band at the reduced transmission power in the second time slot in accordance with the second configuration information and the third configuration information, thereby reducing intermodulation interference.

Furthermore, when the control data only includes control signaling, each of the second configuration information and the third configuration information may include a second interference coordination policy, and the second interference coordination policy may include: that the UE delay sending the uplink transmission in both the first frequency band and the second frequency band for the duration of the second time slot, or a second set power value at which the power of the transmission has to be reduced transmission. In this way, according to the second coordination policy of received interference, the UE may delay sending the uplink transmission in both the first and second frequency bands for at least the duration of the second time slot, or send the uplink transmission in both the second and second frequency bands. first frequency band as in the second frequency band at a transmission power reduced by the second set power value.

Delaying sending the uplink transmission in both the first frequency band and the second frequency band for at least the duration of the second time slot is a case of stopping the uplink transmissions in the first frequency band and in the second frequency band in the second time slot.

In the example, after receiving the second configuration information and the third configuration information sent by the base station, and according to the second configuration information and the third configuration information, the uplink transmission in both the first frequency band and in the second frequency band may be stopped in the second time slot or the uplink transmission in both the first frequency band and the second frequency band may be sent at the reduced transmit power in the second time slot, reducing thereby intermodulation interference.

Fig. 5 is a signaling flow diagram illustrating an interference coordination method according to an example of the present application.

This example is described from the point of view of the interaction between a base station and a UE. As shown in Fig. 6, the interference coordination method includes steps S601-S604.

In step S601, the UE notifies interference tolerance capability information thereof to the base station.

In step S602, the base station receives the interference tolerance capability information of the UE, and, based on the interference tolerance capability information of the UE and the information about the UE accessing a network, determines that interference exists. of intermodulation between the uplink transmission in both a first frequency band and a second frequency band and a downlink transmission in the first frequency band by the UE.

Fig. 7 is a block diagram illustrating an apparatus for coordinating interference according to an example. The apparatus for coordinating interference may be provided at a base station. As shown in Fig. 7, the interference coordination apparatus includes a determination module 71 and a coordination module 72.

The determination module 71 is configured to determine whether there is interference in the device between uplink and downlink transmissions by the UE in two frequency bands.

In this example, the base station can determine whether there is in-device interference between uplink and downlink transmissions by the UE in the two frequency bands based on information about the UE accessing a network in the that interference in the device may include harmonic interference and intermodulation interference.

When integer multiples of one frequency band overlap at least partially with another frequency band, harmonic interference can occur between uplink and downlink transmissions in these two frequency bands.

Intermodulation interference (IM interference) refers to the fact that when two or more interfering signals are added to a receiver at the same time, due to a non-linear effect, the frequencies of the resulting components formed by the interfering signals are sometimes the same. or close to a frequency of a desired signal, and thus the resulting components pass directly through the receiver and cause interference.

The coordination module 72 is configured to, when the determination module determines that interference exists in the device between the uplink and downlink transmissions in the two frequency bands by the UE, to send configuration information to the UE, in in which the configuration information is used to indicate to the UE that, in a time interval during which a base station sends downlink transmission control data in one of the two frequency bands, to stop the uplink transmission in at least one of the two frequency bands or perform power reduction for the uplink transmission in the at least one of the two frequency bands.

In this example, if the base station determines that device interference, such as harmonic interference or intermodulation interference, exists between the uplink and downlink transmissions by the UE in the two frequency bands, the base station The base station may send configuration information to the UE, and the UE may stop an uplink transmission in at least one of the two frequency bands in a time interval during which the base station sends control data of a downlink transmission. in one of the two frequency bands according to the configuration information, thereby avoiding interference for a control channel in the device. And the UE may also perform power reduction for an uplink transmission in at least one of the two frequency bands in a time slot during which the base station sends the downlink transmission control data in one of the two frequency bands. the two frequency bands according to the setting information, thereby achieving a goal of reducing interference for the control channel in the device.

In one example, the coordination module 72 may be configured to, when it is determined that harmonic interference exists between the uplink transmission in a first frequency band and the downlink transmission in a second frequency band by the UE, determine a first time interval during which downlink transmission control data in the second frequency band has to be sent, and sending first configuration information to the UE, wherein the first configuration information is used to indicate to the UE UE that, in the first time slot, stops the uplink transmission in the first frequency band or sends the uplink transmission in the first frequency band at a reduced transmission power.

The control data may include control signaling and a reference signal, or may include only control signaling. Control signaling may include, but is not limited to, a PDCCH. The first Configuration information may be carried in broadcast signaling, upper layer signaling, or physical layer control signaling, sent by the base station.

In this example, after the base station determines that harmonic interference exists between the uplink transmission in the first frequency band and the downlink transmission in the second frequency band by the UE, the base station can determine a first time interval during which downlink transmission control data has to be sent in the second frequency band, and send first configuration information to the UE, so that the UE can stop the uplink transmission in the second frequency band. first frequency band or sending the uplink transmission in the first frequency band at a reduced transmission power in the first time slot.

Taking Figure 2B as an example for description, after the base station determines that the harmonic interference exists between the uplink transmission in the LTE frequency band and the downlink transmission in the NR frequency band by the UE, the base station may determine a first time slot for sending downlink transmission control data in the NR frequency band, and send first configuration information to the UE. After receiving the first configuration information, the UE may stop uplink transmission in the LTE frequency band at the first time slot according to the first configuration information, to avoid harmonic interference. After receiving the first configuration information, the UE may also send the uplink transmission in the LTE frequency band at a reduced transmission power according to the configuration information, to reduce harmonic interference.

Furthermore, when the control data only includes control signaling, the first configuration information may include a first interference coordination policy, and the first interference coordination policy may include: that the UE delay sending the transmission of uplink in the first frequency band for the duration of the first time slot, or a first set power value at which the transmit power is to be reduced. In this way, after receiving the first configuration information, according to the first interference coordination policy, the UE can delay sending the uplink transmission in the first frequency band at least for the duration of the first time slot, or sending the uplink transmission in the first frequency band at a transmission power reduced by the first set power value. Delaying sending the uplink transmission in the first frequency band at least for the duration of the first time slot is a case of stopping the uplink transmission in the first frequency band in the first time slot.

In another example, the coordination module 72 may be configured to, when it is determined that intermodulation interference exists between the uplink transmission in both a first frequency band and a second frequency band and the downlink transmission in the first frequency band by the UE, determining a second time interval during which downlink transmission control data in the first frequency band has to be sent, and sending second configuration information and third configuration information to the UE , wherein the second configuration information is used to instruct the UE to, in the second time slot, stop the uplink transmission in the first frequency band or send the uplink transmission in the first frequency band to a reduced transmit power, and the third configuration information is used to indicate to the UE that, in the second time slot, stop the uplink transmission in the second frequency band or send the uplink transmission in the second frequency band at the reduced transmission power.

The second configuration information may be carried in broadcast signaling, upper layer signaling, or physical layer control signaling, sent by the base station, and the third configuration information may also be carried in broadcast signaling, upper layer signaling. or physical layer control signaling, sent by the base station.

In this example, after the base station determines that intermodulation interference exists between the uplink transmission in both the first and second frequency bands and the downlink transmission in the first frequency band by the UE, the base station may determine a second time slot for sending the downlink transmission control data in the first frequency band, and send the second configuration information and the third configuration information to the UE. Thus, in the second time slot, the UE may stop the uplink transmission in the first frequency band or send the uplink transmission in the first frequency band at a reduced transmission power, and in the second time slot of time, the UE may stop the uplink transmission in the second frequency band or send the uplink transmission in the second frequency band at a reduced transmission power, thereby reducing intermodulation interference.

Taking Figure 2C as an example for description, after the base station determines that the intermodulation interference between the uplink transmission in both the LTE frequency band and the NR frequency band and the downlink transmission in the LTE frequency band by the UE, the base station can determine a second slot of time during which the downlink transmission control data is sent in the LTE frequency band, and sending second configuration information and third configuration information to the UE. After receiving the second configuration information and the third configuration information, the UE may stop the uplink transmission in both the first frequency band and the second frequency band at the second time slot according to the second configuration information and the third configuration information, to avoid intermodulation interference. After receiving the second configuration information and the third configuration information, the UE may also send the uplink transmission in both the first frequency band and the second frequency band in the second time slot at a reduced transmit power according to the second configuration information and the third configuration information, to reduce intermodulation interference.

Furthermore, when the control data only includes control signaling, each of the second configuration information and the third configuration information may include a second interference coordination policy, and the second interference coordination policy may include: that the UE delay sending the uplink transmission in both the first frequency band and the second frequency band for the duration of the second time slot, or a second set power value at which the power of the transmission has to be reduced transmission. In this way, according to the received second interference coordination policy, the UE can delay sending the uplink transmission in both the first frequency band and the second frequency band for at least the duration of the second time slot , or sending the uplink transmission in both the first frequency band and the second frequency band at a transmission power reduced by the set second power value. Delaying sending the uplink transmission in both the first frequency band and the second frequency band for at least the duration of the second time slot is a case of stopping the uplink transmissions in the first frequency band and in the second frequency band in the second time slot.

In the example, when it is determined that the interference exists in the device between the uplink and downlink transmissions in two frequency bands by the UE, the configuration information is sent to the UE, so that the UE can stop the transmission. uplink transmission in at least one of the two frequency bands or perform power reduction for the uplink transmission in the at least one of the two frequency bands in a time interval during which the base station sends data downlink transmission control in one of the two frequency bands, thereby achieving the goal of reducing interference for the control channel in the device.

The first frequency band may belong to a frequency band for LTE, and the second frequency band may belong to a frequency band for NR. Alternatively, the first frequency band and the second frequency band may also belong to two frequency bands for NR respectively.
